Abstract: A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator and configured to reciprocate in an axial direction, the reciprocating pump being configured to suck the fuel when the boosting piston moves in a first direction and configured to boost and eject the fuel when the boosting piston moves in a second direction; and a controller configured to control driving of the linear actuator so as to adjust an amount of the fuel ejected from a boosting cylinder per reciprocating time by adjusting a ratio of a fuel ejection time and a fuel suction time of the reciprocating pump without changing the reciprocating time of the boosting piston in accordance with a load of the internal combustion engine. The adjustment adjusts a stroke length of the boosting piston and a moving speed of the boosting piston in the second direction.

Abstract: A fuel supply device for supplying fuel into a combustion chamber of an internal combustion engine is provided. The device includes: a low pressure fuel supply pipe to which a low pressure fuel is supplied; a high pressure fuel supply pipe to which high pressure fuel to be supplied into the combustion chamber is supplied; fuel supply units provided between the low pressure fuel supply pipe and the high pressure fuel supply pipe, each of the fuel supply units being configured to boost the fuel in the low pressure fuel supply pipe and supply the boosted fuel to the high pressure fuel supply pipe; and a control unit configured to control the fuel supply units. The control unit controls the fuel supply units such that a total amount of ejection of the fuel ejected from the fuel supply units per unit time is close to a constant value.

Abstract: A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator, configured to axially reciprocate, and configured to alternately repeat suction of the fuel and ejection of the fuel more boosted than the fuel at a time of suction by reciprocation of the boosting piston; and a controller to control driving of the linear actuator. When reciprocation amplitude of the boosting piston is A (A>0) and a reciprocating cycle time is T, the controller controls the linear actuator so a maximum value of an absolute value of acceleration when the reciprocating pump sucks the fuel with an absolute value of speed of the boosting piston increasing is smaller than A·(2?/T)2, and so a maximum value of the absolute value of the acceleration of the boosting piston when the reciprocating pump ejects the fuel is larger than A·(2?/T)2.

Abstract: The invention provides important intermediate compounds for the synthesis of acidic glycolipids which are identical with the glycolipid antigens isolated from the acidic glycolipid fractions of peripheral nerve and embryonic central nervous system and preparation methods thereof. By the adoption of the present intermediate compounds, sulfation of 3-hydroxyl group of end glucuronic acid portion of the acidic glycolipid can be quite easily carried out and total synthetic yield be greatly improved.

Abstract: An anchoring apparatus for a floating offshore structure comprising a mooring plug adapted to rotate relatively to the floating offshore structure. From the mooring plug, an even number of anchor cables are radially stretched to the seabed. On the mooring plug, two mobile windlasses are mounted, which can move under any pair of the even number of diametrically opposed anchor cables, and which haul the pair of anchor cables while holding them with a warping drum and a pressing drum.
